A Hudson Valley woman is finger lickin’ mad at Kentucky Fried Chicken, claiming its understuffed buckets are for the birds.

Anna Wurtzburger, of Hopewell Junction, says she bought a $20 bucket of chicken from KFC over the summer and was disappointed to find it looked much different than what’s in the chain’s ads.

“I came home and said, ‘Where’s the chicken?’ I thought I was going to have a couple of meals,” she told The Post.

“They say it feeds the whole family … They’re showing a bucket that’s overflowing with chicken,” the 64-year-old widow griped. “You get half a bucket! That’s false advertising, and it doesn’t feed the whole family. They’re small pieces!”

Wurtzburger rang up the fast-food giant’s Georgia headquarters to complain, and was told the chicken was portrayed prominently on the commercial “so that the public could see the chicken.”

“If you want the public to look at your chicken, put it in a dish,” she fumed. “It’s a lot of BS. … I expect to get what you’re telling me.”

Putting her money where her hungry mouth is, Wurtzburger hired a lawyer and filed a lawsuit, demanding KFC change its advertising.

She also returned two gift certificates the company sent her as a mea culpa.

“You know what commercial they should put on? You remember the movie, ‘Oliver’?” she said. “It was about the little boy growing up in the orphanages and he was hungry and he goes to the man, ‘Can I have some more?’ ”

Retired from the Fishkill Correction Facility, Wurtzburger lives off her Social Security check and said the KFC meal was supposed to be a rare treat.

The grandmother seeks $20 million in damages. KFC called the lawsuit “meritless.”
